Embodiment Construction
[0030] Hereinafter, the form for carrying out this invention is demonstrated in detail.
[0031] The gas-shielded arc welding flux-cored wire of this embodiment (hereinafter, appropriately referred to as "welding wire" or "flux-cored wire") is a wire used in gas-shielded arc welding, and is a wire in which a steel sheath is filled with flux.
[0032] Specifically, the welding wire according to the present embodiment is composed of a cylindrical steel sheath and flux filled inside the steel sheath. In addition, the welding wire may be of a seamless type without a seam on the steel sheath or a seam type with a seam on the steel sheath. In addition, the welding wire may or may not be plated on the surface (the outer side of the steel sheath).
[0033] In addition, the wire diameter (diameter) of the welding wire of this embodiment is not specifically limited, It just needs to be 1.2-2.4 mm. In addition, the flux filling rate of the welding wire is not particularly limited, but ...
